Also known as Cycas revoluta, this palm species is not only toxic to dogs, but also to humans. The seeds and nuts of sago are the most toxic parts of the palm. This palm contains a toxic chemical called ‘cycasin’. When ingested in large quantities (any part of the plant), it can harm the liver and neurological system permanently. Other than this, diarrhea, dizziness, bleeding from orifices, hind-limb paralysis, and seizures are a few signs a dog will show after its ingestion.

Cycas Revoluta, or the Sago Palm, has a deceiving name. It is not a palm at all, but a ‘cycad’. Poisonous to animals and humans. Sago seeds are a yummy treat. They can’t help but enjoy the crunchy nutty flavor.

Concentrations of cycasin, the primary toxin in cycads, are highest in the seeds and roots, but present in all parts of the plant. Ingestion of as few as one to two seeds can be fatal in dogs. Mortality has been reported to vary between 32% and 58%.
